As they continue to investigate three residential burglaries earlier this month in the Green's Farms section of town, Westport police are urging people to secure their homes to ward off burglars.

"We cannot emphasize enough the importance of locking your doors and windows when you sleep at night," said police Capt. Sam Arciola. "These particular individuals are opportunistic, and they're going to take advantage of opportunities that are presented to them."

Each of the three break-ins involved the intruders gaining access to the home through an unlocked entryway, police said.

So far, there have been no arrests.

In the first burglary, a Devon Road resident called police May 6, to report a break-in at his home had taken place between 4 a.m. and 6 a.m.

Entry was apparently gained through an unlocked rear door. The residents reported that a woman's purse and an HP laptop computer were missing. The purse was discovered outside the residence, but a set of car keys, as well as $25 cash, were taken from the purse, police said.

No one in the house heard the intrusion, and no one was injured, police said.

The intruder reportedly left the scene by using the keys to steal the homeowner's gray Honda Civic four-door sedan. The compact car has the Connecticut license plate 561YVT.

Another burglary was reported May 7 nearby on Green's Farms Road, where the homeowner reported the intrusion took place while the occupants were sleeping.

Entry was made through an unlocked door and laptop computers were reported stolen, police said.

Also on May 7, a burglary at another Devon Road home was reported, where the garage was entered overnight through an unlocked foyer. Several vehicles were entered and police are investigating whether any items were taken.

"There's a high probability that we think that these crimes appear to be connected because of the location and time frames," Arciola said.

Arciola also advised residents to call police if they "hear, witness or suspect anything unusual in or around their residences."; 203-255-4561, ext. 118;
